IT depends on the direction it was rolling. If it was rolling horizontal, its initial vertical veloicty was zero, and the initial horizontal veloicty was as given.
Assuming it was horizontal.
Horizontal
d=vt
.75=1.27 t solve for t, this is the time in the air.
Vertical
h=1/2 g t^2 put in t, and solve for h.
